ABSTRACT:
An apparatus for making hollow glassware has at least one preform provided adjacent a turntable rotatable about an upright axis and carrying at least two angularly spaced final molds. The turntable can rotate about this axis so as to orbit the final molds through a transfer position close to the perform and a takeout position angularly offset from the transfer position and remote from the preform. At least one arm is provided above the turntable and final molds and carries at least two respective mold heads. This arm is pivotal about the axis with the mold heads being vertically alignable and engageable with the respective final molds. The arm and mold heads can be pivoted about the axis independently of the turntable and a source of air at a pressure different from ambient is connected to the mold heads through the arm. A parison formed in the preform is deposited into one of the final molds in the transfer position and immediately thereafter one of the mold heads is brought into engagement with the one mold. Thereafter the one mold is orbited around into the takeout position while the mold head is carrying out the blow-molding operation, whereupon the mold head moves to the side to allow demolding of the finished workpiece.
